SD = standard deviation; CI= confidence interval
PSQ = Perceived Sleep Quality PSQI factor
SEf = Sleep Efficiency PSQI factor
DD = Daily Disturbances PSQI factor
Mean dif c/w Ctl = Mean difference between intervention group and control group
P-values come from group comparison T-tests at each time point
Mean difference and effect size are shown in absolute values, so that a positive number indicates benefit (lower PSQI scores), compared to control
